If you run a server with any older version, please upgrade or consider turning off autodownload ( set sv_allowDownload to 0 ). Wolfenstein: Enemy Territory servers http/ftp download feature is not affected by CVE-2006-2082. If you don't wish to upgrade, you can decide to only enable http/ftp downloads and disable legacy downloads in that particular case.

Finally, server administrators should note that game servers should be running in restricted environments as much as possible ( unpriviledged accounts and chroot jails ). It's a good thing to do the same for clients, or at least ensure that you are properly firewalled.
